This plane (the Emergency Transport Aircraft 1) is a long range supersonic transport used as a flying ambulance. In fact the plane is designed to transport medical equipment or hospital treatment needing people at record speed to save as many lives as possible. The plane has different max speeds: 750 km/h in subsonic mode (throttle), 2100 km/h in supersonic mode (AG1 and 0 throttle) and 2500 km/h in boost mode (AG1+ 100% throttle). The plane is specially designed to land on short runways thanks to it's powerfull brakes that can be helped by it's 3 parachutes (AG4). During landing i recommend to keep your speed at 380 km/h with trim all the way up. These are some other controls (AG2 for droop snoot, AG3 for cargo door)
